Direct contact - 2 cells short distance.

Describe how phosphorylation propagates signal information. The signal is transmitted by a cascade of protein phosphorylations each causing a shape change because of the interaction of the newly added phosphate groups with charge or polar amino acids on the protein being phosphorylated. Protein phosphorylation a common mode of regulation in cells is a major mechanism of signal transduction Certain small molecules and ions are key components of signaling pathways 2nd messengers Cellular Responses to Signals In response to a signal a cell may regulatae activities in the cytoplasm or transcription in the nucleus.
